Square Enix has just released a new trailer for Deus Ex: Human Revolution, and it shows off a lot of gameplay clips featuring the main character, Adam Jensen.

Body modifications played a major role in the earlier Deus Ex titles, and you’ll see a lot of them put to good use in the following video, which shows Jensen using nanotech in lots of stealth and combat scenes.

Published by Square Enix, Deus Ex: Human Revolution is scheduled for release on PC, Xbox 360 and PlayStation 3 in “early 2011.”

In addition, BioWare plans to release the previously announced Overlord DLC for Mass Effect 2 on Tuesday. The new mini-campaign of five levels on one planet where you have to fight off an alien AI, will be sold for 560 BioWare points (about $7).

In the demo, players step into the role of Commander Shepard and must escape from a Cerberus space station under siege. Players can jump ahead to a later mission where they must rescue Subject Zero, a hardened, dangerous criminal from a heavily guarded prison ship.

Once they play the demo, players will be able to create a save and carry over their character along with the experience points, story decisions, achievements and weapons earned into the full version of the game – picking up right where they left off, on both PC and Xbox 360.

BioWare also announced today that players already in the game can download a new game add-on called “Overlord”, adding five new areas and two new achievements.

Available June 15, the game add-on is available for 560 Microsoft points and on PC for 560 BioWare points. Also on June 15, BioWare is releasing a new premium theme based on Omega and new avatar items for Xbox Live will follow on June 17.
